Smart WiFi Blind Switch Meross MRS100MA (Matter) — in-wall motorized blind controller, EU version

The Meross MRS100MA(EU) Smart WiFi Blind Switch converts traditional roller blinds into a smart, automated system. It supports a wide input voltage range (100–240 V~) and controls motors with up to 400 W output, connects via 2.4 GHz Wi‑Fi and is compatible with the Matter standard for integration with common smart home ecosystems.

Advantages

The switch offers temperature-based automation, flexible scheduling tied to time or sunrise/sunset, and remote control through the Meross app. Matter support enables direct integration with Apple Home (HomeKit), Amazon Alexa, and Google Home. Built-in LED backlight and stable operation across a wide voltage range improve everyday usability and reliability.

Suitable for

• Automating roller blinds and shutters with motor power up to 400 W
• Homes and apartments with standard 100–240 V electrical installations
• Integration into smart home setups using Meross app, Matter, HomeKit, Alexa, or Google Home

When it may not be suitable

The switch is not suitable for controlling motors that exceed 400 W or for installations that require a different voltage range than 100–240 V. It requires a 2.4 GHz Wi‑Fi network and a compatible smartphone (iOS 10+/Android 6.0+) for initial setup and advanced features; without these, functionality will be limited.

How to use

Install the switch in line with the roller blind motor following local electrical safety rules and the manufacturer’s wiring instructions. Connect the device to a 2.4 GHz Wi‑Fi network, then configure it in the Meross app for scheduling, temperature-based automation, and remote control. Enable Matter integration in the app to add the device to Apple Home, Amazon Alexa, or Google Home for voice control and ecosystem routines.

What to consider before purchase

• Confirm the blind motor’s power does not exceed 400 W
• Ensure your home Wi‑Fi uses 2.4 GHz and provides sufficient coverage at the installation point
• Verify your smartphone meets system requirements for the Meross app
• Check compatibility with your preferred smart home ecosystem if voice control or integration is required

Usage recommendations

For reliable operation, place the device where Wi‑Fi signal strength is stable and set schedules based on local sunrise/sunset or typical daily routines. Disable the LED backlight via the app if you require complete darkness in sleeping areas.
